Referring now to Fig. '1', 10 generally indicates a supportsubstantially in the shape of a casing.

The rear end portion of a seat I2 is pivoted to the support I0 at M. Aback-rest I6 is pivotally mounted on the support I0 at I8 at a pointspaced from the pivotal connection I4 between the seat l2 and thesupport In. The back-rest [6 has a downward extension 20 projectingdownwardly below the plane of the seat 12. The adjustable recliningchair comprises at each of its sides a link-chain including a bent lowerconnecting link 22 and a front connecting link 24 pivotally connectedwith each other at 26. The rear end of said link-chain, i. e., the rearend portion of the lower connecting link 22, is pivoted to the downwardextension 20 of the back-rest It at 28; the front end of the link-chain,i. e., the upper end portion of the front connecting link 24, is pivotedto the seat l2 at 30. Said seat [2, said downward extension 20 of theback-rest I6 and said link-chain 22, 24 form the movable members of alink-system swingably mounted on the support ID as described above. Themovements of the movable members of said linksystem are controlled byguiding means or a guiding link 32 associated with the support H] and alink of the link-chain; accordin to Fig. 1, one end of the guidin link32 is pivoted to the support ID at 34, the'other end of said guidinglink 32 is pivotally connected with an intermediate point of the lowerconnecting link 22 at 36.

A leg-rest 33 is swingably mounted on the front portion of the seat l2at 49. On each side of the chair, one end of a controlling link 42passing through a slot A l of the front wall of the casing like supportH3 is pivoted to said leg-rest 38 at 46, the other end of saidcontrolling link 42 is pivoted to an intermediate point of the lowerconnecting link 22 at lii. Thus, the movements ofthe vswingable leg-rest38 are controlled by the controlling link 11 2 in dependence on themovements of the lower connecting link 22 of the link chain 22, 245'.

The sitting position of the movable members of the chair is limited bythe upper edge of the,

casing-like support lil on which the seat l2 comes to a rest. When theo'ccupant of the chair leans the weight of his body against theback-rest it and,, swings,s.ame into a reclinedposition, for ex ample,the extreme]reclinedpo sition it limited bythe edgeim of the. rear wallof the support It n ratin w th t b ck e h ea 1 is swung into thereclined position I2 through the medium of above described link-system,and the leg-rest 38 is brought into the substantially horizontalposition 38 through the medium of the controlling link 42 arrangedbetween the legrest 38 and the lower connecting link 22.

As best shown in Figs. 1 and 2, the adjustable reclining chair isprovided with a locking device generally indicated by 52. Said lockingdevice 52 comprises a rockable lever 54 swingably mounted on theswingable seat I2 at 56. Said rockable lever 54 is provided with ahandle 58 for manual actuation. Furthermore, said rockable lever 54 isprovided with a slot 60 and a notch 62 communicating with said slot 60at one side thereof. A stationary locking pin 64 or the like mounted ona side wall of the support I is arranged for engagement with said slot60 on said notch 62. A tension spring 66 stretched between a point 68 ofsaid rockable lever 54 and a point of the seat I2 tends to urge saidnotch 62 into locking engagement with said locking pin 64 when saidlocking pin 64 is in register with said notch, as shown in Figs. 1 and 2in full lines. When the locking pin 64 and the notch 62 are not inregister with each other as shown in dash-and-dot lines in Fig. 2, thespring 62 tends to urge the side of the slot 60 communicating with thenotch 64 against said locking pin 64'. The notch 62 is arranged at sucha point of the lever 54, that said notch 62 is in register with saidlocking pin 54 when the seat I2 and the other movable members of thechair are in their sitting position. Therefore, when the movable membersof the chair are brought from a reclined position into the sittingposition, the locking pin 64 snaps automatically into the notch 62 bythe action of the spring 66, whereby the movable members of the chairare mechanically locked in the sitting position. If it is desired tobring the movable members of the chair from the sitting position into areclined position, the rockable lever 54 is swung in counter-clockwisedirection (as viewed in Fig. 2) by means of the handle 58, whereby thelocking pin 64 is brought into register with the slot 60. Thereupon themovable members of the chair may be brought into a reclined position, asnow the slot 60 may slide along the locking pin 64. As, after a releaseof the handle 58, the spring 66 urges a side of the slot 60 against thelocking pn 64, a friction is caused between the lever 54 and the pin 64which may be of sufficient degree to hold or to assist in the holding ofthe tion, the rockable lever 54 must be swung by means of the handle 58aabout the pivot 56a in counter-clockwise direction so as to bring thelocking pin 64a and the slot 60a in register with each other.

Of course, the reclining chair shown in Fig. 1

may also be equipped with another locking demovable members of the chairin any intermediate position.

According to the embodiment of a locking device 52a shown in Fig. 3, therockable lever 54:; is provided with a slot a communicating with aseries of notches 62a. The uppermost notch 32a is arranged in such aposition that it snaps automatically into engagement with the lockingpin 64a mounted on the support by the action of the spring 66a when theseat l2 and the other movable members of the chair are in their sittingposition. The lowermost notch 62a is arranged in such a position that itautomatically snaps into locking engagement with the locking pin 64a bythe action of the spring 6611 when the seat I2 and the other movablemembers of the chair are in their extreme reclined position. Thearrangement of a series of notches 62a. permits the mechanical lockingof the movable members of the chair in several predetermined positions.Of course, each time when the movable members of the chair shall bereleased from a locked posivice, if desired.
